<h2>Remarks</h2>
<p>This extension is useful only when the dump file is a System Crash File (.dmp) that has not been converted to a minidump file from a kernel or full dump file, or the live system has finished starting and is online (for example, at the log-in prompt).</p>
<p>You can use any combination of the <b>-debug</b>, <b>-devices</b>, <b>-memory</b>, <b>-power</b>, <b>-processor</b>, <b>-system</b>,  and <b>-v</b> parameters in a single extension command.</p>
<p>The following parameters are supported only on particular systems: </p>
<ul>
<li>
<p>The <b>gbl</b> parameter works only when the target computer supports ACPI. </p>
</li>
<li>
<p>The <b>smbios</b> parameter works only when the target computer supports SMBIOS. </p>
</li>
<li>
<p>The <b>registers</b> parameter does not work on Itanium-based target computers, because they do not collect MSRs.</p>
</li>
</ul>
<p>Microsoft makes every effort to remove personally identifiable information (PII) from these records. All PII is removed from dump files. However, on a live system, some PII may not yet be removed. As a result, PII fields will be reported as 0 or blank, even if they actually contain information. </p>
<p>To stop execution of commands that include the <b>cpuinfo</b>, <b>gbl</b>, <b>registers</b>, or <b>smbios</b> parameters at any time, press CTRL+BREAK (in WinDbg) or CTRL+C (in KD).</p></div></div>
